Consider COVID-19 when a child presents with severe croup in summer

Coronavirus disease-2019 (COVID-19) has rapidly disseminated worldwide. In children, the most prevalent manifestations of COVID-19 are fever, cough, and fatigue.

Here, we describe a case of croup secondary to COVID-19 with a preexisting laryngomalacia who presented with fever, dyspnea, and severe cough. The patient had respiratory stridor and diffuse wheezing on lung auscultation.

Although a certain association between COVID-19 and croup has yet to be proven; but as it showed, SARS-CoV-2, like other viruses, can be a leading cause of croup. Therefore, we suggest in children with croup and upper airway symptoms, SARS-CoV-2 infection be ruled out.
